Standard and Extensible

CommonMark + GFM Specifications

Today CommonMark is the de-facto Markdown standard. GFM (GitHub Flavored Markdown) is another popular specification based on CommonMark - maintained by GitHub, which is the Markdown mostly used.
TOAST UI Editor respects both CommonMark and GFM specifications. Write documents with ease using productive tools provided by TOAST UI Editor and you can easily open the produced document wherever the specifications are supported.

Powerful Extensions

CommonMark and GFM are great, but we often need more abstraction. The TOAST UI Editor comes with powerful Extensions in compliance with the Markdown syntax. You also get the flexibility to develop your own extensions using simple APIs.

Here are some of the extensions you can start with:

Color picker: ColorPicker provides an easy way to color text with a GUI tool box

Features

TOAST UI Editor provides Markdown mode and WYSIWYG mode.

Depending on the type of use you want like production of Markdown or maybe to just edit the Markdown. The TOAST UI Editor can be helpful for both the usage. It offers Markdown mode and WYSIWYG mode, which can be switched any point in time.

Productive Markdown mode

Live Preview: Edit Markdown while keeping an eye on the rendered HTML. Your edits will be applied immediately

Scrolling Sync: Synchronous scrolling between Markdown and Preview. You don't need to scroll through each one separately

Be careful not to load both the editor and the viewer at the same time because the editor already contains the viewer function, you can initialize editor Editor.factory() and set the viewer option to value true in order to make the editor a viewer. You can also call getHTML() to render the HTML.

TOAST UI Editor respects CommonMark and GFM. So any Markdown renderer including markdownit can handle the content made using TOAST UI Editor. You can also use any of these renderer in place of TOAST UI Editor Viewer.
